Abstract

A tubular connector made from a sheet metal element (10) bent into tubular shape and having overlapping ends. Sealing rings (20) are positioned around the connector and preferably held in position by means of steel band (23) which are fixed around the connector and provided with a predetermined breaking point. The connector has a slightly smaller diameter than that of the pipes to be joined together and is expanded after insertion into the pipes by means of a screw device (13) connected with the axial ends of the pipe, the steel band (23) breaking and the seals being compressed between the outer periphery of the connector and the inner periphery of the joined-together pipes. A sealing cloth provided with folds or a strip of resilient material is connected with the overlapping ends of the connector.
